Vanda plant named &#39;SPCDW0901&#39;

ABSTRACT

A new and distinct  Vanda hybrid  cultivar named ‘SPCDW0901’ is disclosed, characterized by unique purple coloration of the petals and overall, compact plant habit and unusual low temperature tolerance. The new variety is a  Vanda , and is normally used as an ornamental plant.

LATIN NAME OF THE GENUS AND SPECIES

Vanda hybrid

VARIETY DENOMINATION

‘SPCDW0901’

BACKGROUND OF THE INVENTION

The new cultivar was discovered as a chance, naturally occurringmutation of the unpatented commercial variety Vanda hybrid ‘Blue Magic.’The inventor, Mr. Thumrong Suphachadiwong, a citizen of Thailand,discovered the new variety as a chance mutation among several hundredplants produced at a commercial laboratory in Chonburi, Thailand. Thenew variety was discovered in May 2003 by the inventor.

Asexual reproduction of the new cultivar ‘SPCDW0901’ by tissue culturewas performed at a commercial laboratory in Chonburi, Thailand later in2003. Since that time, multiple generations have been reproduced, andhave shown that the unique features of this cultivar are stable andreproduced true to type through successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘SPCDW0901’ has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, day length, and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘SPCDW0901.’ These characteristics incombination distinguish ‘SPCDW0901’ as a new and distinct Vanda hybridcultivar:

1. Compact overall plant

2. Unique purple and white flower coloration

3. Unusually good tolerance for colder temperatures

PARENT COMPARISON

Plants of the new cultivar ‘SPCDW0901’ are similar to plants of theparent variety unpatented Vanda hybrid ‘Blue Magic’ in mosthorticultural characteristics. However, plants of the new cultivar‘SPCDW0901’ produce purple and white colored flowers compared to theblue and white flowers of ‘Blue Magic.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘SPCDW0901’ are similar to plants of theunpatented commercial variety, Vanda hybrid ‘Pink Magic’ in mosthorticultural characteristics. However, plants of the new cultivar‘SPCDW0901’ produce purple and white flowers, whereas ‘Pink Magic’produces pink and white colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color atypical plant of ‘SPCDW0901’ grown in a greenhouse. The pot size is acommercial 11 cm container. The plant shown is approximately 5 yearsold. The photograph was taken using conventional techniques and althoughcolors may appear different from actual colors due to light reflectanceit is as accurate as possible by conventional photographic techniques.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart except where general terms ofordinary dictionary significance are used. The following observationsand measurements describe ‘SPCDW0901’ plants grown in a commercialgreenhouse in Honselersdijk, the Netherlands. Temperature ranged from23° C. during the day and 19° C. at night. Light levels were at aminimum of 10,000 lux, including supplemental lighting given duringnaturally dark periods. During the naturally darkest days supplementallighting of 10,000 lux was given for 16 hours per day. Measurements andnumerical values represent averages of typical flowering types. Nochemical or photoperiodic treatments were given.

-   Botanical classification: Vanda hybrid SPCDW0901.’

PROPAGATION

-   Type of propagation typically used: tissue culture-   General propagation: The time needed from the start of a mericlone    to get the small plants ready for deflasking is approximately 24    months under a controlled temperature of about 26 degrees Celsius.    After that period they have matured roots. Young tissue culture    plantlets start to make roots after approximately 18 months in    flasks.-   Root description: Moderately to heavy rooting with aerial roots    only. Roots very fleshy, non-fibrous. Average length of old roots:    37.9 cm, average diameter of old roots: 2 mm. Average length of    young roots: 28.9, average diameter of young roots: 7 mm. Old roots    colored near RHS Yellow-Green 147C. Young roots colored near RHS    Greyed-Green 192D.
